Determine the minimum coefficient of static friction $\backslash$mu $\_($s$)$ which will allow the drum with fixed inner hub to be rolled up the $18\backslash$deg incline at

a steady speed without slipping. What are the corresponding values of the force P and the friction force F $?$

Answers:

$\backslash$mu $\_($s$)=$i$,$

P$=$i$^(2),$mg

F$=,$mg
